GLASS-TANK.

Specification of Letters Patent.

'Patented Aug. s, 1905.

Application filed October 3l, 1904. Serial No. 230,816.

To all whom t may concern:

Be it known that I, WILLIAM EMIL BooK, a citizen ofthe United States,residing at Toledo, in the county ot' Lucas and State of Ohio, haveinvented certain new and useful Improvements ing or dipping operations,as more fully here-` inafter described, and particularly pointed out inthe claims.

In the drawings, Figure l is a top plan view of the tank embodying myinvention. Fig. 2 is a front perspective view thereof. Fig. 3 is a sideelevation, partly in section; and Fig. 4 is a vertical section on line mfr of Fig. I.

A represents the melting-tank, which may be supplied with a heatingmedium by any ordinary and suitable means. I do not deem it necessary toillustrate the heating means, as such heating means are well known andordinarily consist ot' a gas-supply passing through a checker-'work onopposite sides of the tank and discharging into the heatingchamber Babove the glass-level therein.

Cis apartition across the tank, dividingthe melting-chamber B from theplaning or working chamber D, the two being connected at the bottomthrough a passage F, and preferably at the top through a passage E, sothat there will be heat over the entire mass of glass and so that themelted glass will pass from the chamber' B into the chamber D.

The top of the tank comprises the stationf Aary portion G and themovable portion H.

The movable portion H, I prefer to construct as shown in Figs. l and 2,in which I is a Aframe-for instance, as ot' cast-iron-supporting thetire-clay or brick portion J, which portion is provided with a port orports K. The frame I has the end brackets L, supported on the wheels M,which in turn are supported on the tracks N at opposite sides of thefurnace.

The ports K extend over the molten glass within the tank, so as toexpose such glass as is beneath the ports for dipping or gatheringoperations by any suitable means.

The movable part ot' the top is provided with any suitable actuatingmeans, which will intermittently or periodically reciprocate the same,so that the ports K will expose different or fresh portions of themolten glass -in the tank. This movement may be accomplished by anysuitable mechanism, suoli as a crank or apiston, and it is so obviousthat I do not deem it necessary to illustrate it. I have shown aconnecting-rod O, to which said operating device may be connected.

The parts being thus constructed, their operation is as follows: Ingathering the glass, the cover being in the position shown in Fig. 2,the operators dip their blo w-irons or purityrods into the glass exposedby the ports K either successively or simultaneously, as desired, andthen the movable cover is reciprocated, so that a portion ot' the glasspreviously exposed and in which the dipping took place is covered by theimpertorate portions P between the ports, while new or fresh portions ofthe glass in the tank are exposed for dipping or gathering operations.

While I have shown this specific apparatus, it is obvious that myinvention is susceptible of expression in many different forms, and I donot desire to be limited to the precise construction herein shown, as Ibelieve Iam first to construct a glass tank or lfurnace having a topwith a port and means for effecting the relative movement between saidtank and top to expose different portions of the glass in the tankthrough a port for gathering.

What I claim as my invention is- 1. The combination of a glass tank orfurnace having a top, of means for horizontally movinga portion ot' saidtop to present an opening through which the glass may be gathered.

2. The combination of a 'glass tank or furnace, a top thereover, andmeans for horizontally moving a portion ot' said top to periodicall yexpose a portion of the glass in the tank.

3. The combination ot' a continuous melting-tank, having aplaning-chamber, of a top for said chamber, and means Afor horizontallymoving a portion of said top to expose the glass in said chamber forgathering.

4. The combination of a glass tank or holder, oi' a top therefor, andmeans for moving a portion of said top to periodically expose differentportions of said tank or holder for gathering purpose.

5. The combination of aglass tank,aholder, of a top therefor, having aport adapted to expose a portion of the glass, and means for moving aportion of said top to expose different portions of the glass in thetank through said port.

6. The combination of a glass tank or furnace, having a top, and meansfor reciprocating a portion of said top to expose different portions ofthe glass in said tank periodically.

7. The combination of a glass tank or furnace, having a top, ports insaid top, and means for eti'ecting a relative movement between said tankand a portion of said top to periodically expose different portions ofthe glass in the tank through said ports.

8. The combination, in a glass tank or furnace having a top and a portin. said top, of means for moving a portion of said top to change theposition of said port in relation to the body of glass in the tank.

9. The combination, in a glass tank or furnace having a top and a portin said top, oi' means for moving a portion of said top to periodicallychange the position of said port in relation to the body of glass in thetank.

l 10. rIhe combination of a stationary glass tank or furnace having' amovable top and a port in said top, of means for exposing differentportions of the glass in said tank through said port.

ll. The combination with a continuous melting-tank, having a stationaryplaningchamber, of a top for said chamber and means for periodicallyexposing different portions oi' the glass in said chamber for gathering.

In testimony whereoi` I affix my signature in presence of two witnesses.

WILLIAM EMIL BOCK.
